FRI/{K H. rrvoe rm/rssswa I BY Ann/(M5) United States Patent 3,006,516 GARMENT FINISHER AND MEANS FOR CON- TROLLING FLGW OF PROCESSING FLUIDS THERETO Frank H. Riehterlressing, Louisville, Ky., assignor to W. M. Cissell Manufacturing Company, Louisville, Ky., a corporation of Kenmcky Filed Sept. 5, 1957, Ser. No. 682,147 18 Claims. (Cl. 223-70) This invention relates generally to garment finishers of the type having a distendable, fluid-pervious bag into which air and steam are supplied. In particular, it relates to an improved finisher having means for readily selecting and controlling the flow of such processing fluids into the bag, both as to the timing of the 110w thereof, and as to pressure of the air supplied, thus to increase the capability of the finisher to handle normally difiicult garments, such as chamois or suede lined articles, as well as to improve the efiiciency of the finisher in handling garments of lighter materials. Moreover, the invention, by reason of automatic control features embodied therein, is directed toward the feature of relieving the operator of the necessity of remaining at a fixed station during the cycle of finishing operation.

An object of the invention is to provide an improved finisher having means for supplying steam and full air pressure simultaneously into the finisher bag.

Another object is to provide an improved finisher having an air control means selectively adjustable from a position at which air is bled into the finisher bag in a small amount to a position in which air is forced thereinto in a large amount and under full pressure.

Another object is to provide an improved finisher having a solenoid operated steam supply valve and a motor driven air blower both controlled from a single timer arranged to energize initially the motor and solenoid simultaneously and to de-energize the motor after the solenoid de-energization and after expiration of a suitable drying period.

Another object is to provide an improved damper in the air supply conduit of a garment finisher for preventing the condensation of steam within the finisher.

A further object is to provide an improved finisher having all control means manually operable from a single operating station and normally requiring no continual personal attention of the operator after the finishing cycle is initiated.

Other objects and advantages will become apparent as the description proceeds and when considered in conjunction with the accompanying drawings in which:

In carrying out my invention, I prefer to employ a bag type finisher having a removable inner form mounted for rotary movement upon a stationary base assembly and of the general type more fully disclosed in the copending application of Frank H. Richterkessing and William M. Cissell, Serial Number 586,710, filed May 23, 1956, now Patent No. 2,948,443, granted August 9, 1960. The form is encased in a distendable bag, such as nylon, or the like, and steam and air are supplied from sources within the stationary base assembly. An electro-mechanical arrangement, including appropriate linkages, permits both the motor for driving the blower for supplying air and the solenoid for controlling a valve to release steam, to be operated in a cooperative manner and to function automatically after the selected position of a manually set timer and of a manually set air controller has once been established.

The settings of the timer and air controller are adapted to be chosen from a wide range of processing capacities so that the garments of a wide range of materials, for example, from sheer, delicate garments to heavy fabrics, such as corduroy, chamois or suede garments, may be rapidly finished upon the same machine.

Referring first to FIG. 1, the stationary base assembly includes a hollow base portion 10 having an air conduit 11 leading thereinto and receiving air from a blower 12 driven by electric motor 13. A form encased in a distendable, fiuid-pervious bag 14 is rotatably mounted upon the base assembly and has rigidly fixed thereto a housing 15 serving to mount the handle for a front clamp and a series of improved lever actuated controls for adjusting the periphery of bag 14 to accommodate various sizes and styles of garments, all as more fully set forth in the copending application of Frank H. Richterkessing and Walter M. Ingold, Serial Number 673,360, filed July 22, 1957', and issued as US. Patent 2,889,969. By means of a rigid tube 16 extending from the base portion 10, a conventional automatic timer 17, of the type shown in my copending application Serial No. 519,752, filed July 5, 1955, now abandoned, is mounted at an operating station closely adjacent the normal position of the control levers and handle on the rotatable portion of the apparatus. In addition, an air controller 18, later to be described, is mounted alongside the timer, thus making available to the operator at a single station all of the controls which he normally employs in finishing a garment. Also mounted upon the base assembly is a-solenoid enclosure 19 and a platform 20 for providing a convenient location at which the operator may deposit auxiliary devices, such as clamps, sleevers, and the like, without bending over. An armored cable 21 contains electrical leads between the solenoid enclosure and the motor, it being understood that electrical leads between the timer and solenoid enclosure are contained in the hollow tube 16. Motor 13 preferably runs at constant speed and drives blower 12 at constant speed, the pressure of air being supplied into the entrance of conduit 11 therefore being constant while the motor is running and the pressure of air entering bag 14 being regulated by the setting of a damper located in that conduit and later to be described. It will be understood that different air pressures are required in the bag depending upon the fabric of the garment being processed.

Considering now the diagrammatic showing in FIG. 2, a steam coil 22 is disposed within the base portion 10 above a support plate 23 which is spaced fiom the bottom of the base assembly and which bottom normally rests upon a floor. Steam is constantly supplied to the top of the coil and withdrawn along with any condensate from the bottom of that coil. Adjacent the bottom of the coil which may be provided with radiating fins, not shown, a connection leads into the interior of a steam supply column 24 resting upon plate 23 and having a bearing seat 25 at its upper end upon which the rotatable form and its attachments is adapted to be seated, as more fully set'forth in the copending application Serial Number 673,360 filed July 22, 1957. At an upper portion, the column has a steam distributing member 26 through which steam is dispersed into the interior of the bag when a steam release valve, not shown, contained within the column is opened by movement of a solenoid actuated rod 27, the Valve being biased into normally closed position.

At its lower end, the rod is loosely attached to one arm 28 of a bell crank by means of a short hook portion 9 of the lower end of that rod, which hook extends through a hole near the end of that arm; the bell crank also being provided with a longer arm 29 which extends downwardly exteriorly of the base assembly, the entire bell crankbeing pivotally mounted upon the lower part of the steam column along the axis indicated at 8. Pivotally attached to arm 29 intermediate the ends thereof is a link 30 having a plunger 31 at its outer end, the plunger being disposed within solenoid 32 having terminals 33 and 34. Also pivotally attached to arm 29 adjacent the bottom thereof as by a loosely engaging hook portion 7 is a damper-control-arm-engaging rod 35 journalled in a shift lever 36 for longitudinal movement therethrough. It will be understood that the bias upon the. steam release valve which may be provided, for example, by a compression spring, is such as to hold the. solenoid plunger in retracted position until current is supplied through the solenoid coil and thus the rod 35 is also held normally in retracted position as indicated in FIG. 2.

By means of leads 40 and 41, electrical power is supplied to a conventional relay 42 and thence to contacts on timer 17 and through the timer to the solenoid circuit and to the motor circuit. The timer 17 is of the conventional type having separate circuits to the solenoid and to the motor so that the solenoid and motor are sequentially de-energized with the solenoid being de-energized first. However, upon initiating a cycle, the timer circuits serve to energize the solenoid and motor simultaneously. When motor 13 is energized, it drives blower 12 by any suitable means, not shown, such as a belt drive, and air under pressure is supplied into conduit 11. For clarity, the leads to the contacts on timer 1'7 and to the motor 13' are shown in FIG. 2 as being outside tube 16 and cable 21, whereas, in an actual installation, they are contained therein. The relay 42 is seen in greater detail in FIG. 10 wherein the relay arm 89 connected to terminal 92 is normally held by spring 91 out of contact with terminal 90, but is moved into contact with that terminal 90 when a solenoid 93 connected across terminalsv 94 and 95 is actuated in dependence upon the setting of timer 17. This timer has a suitable switch 96 between its terminals 97 and 98 and a second suitable switch 99 between its terminals 100 and 101. These switches are of conventional construction being adapted to be moved between a position in which they make contact with their respective terminals (seen diagrammatically in dotted lines in FIG. 10) and a position in which they break such contact (seen diagrammatically in solid lines). For example, these switches may be of the type shown in the catalogue of the General Electric Company CRl070-Cl46 known as G.E. size 1 Switchette. Cam followers for these switches cooperate with means such as flexible leaf springs biased to open switch positions, and are in turn actuated by movement of the cam in the timer. Terminals 98 and 101 are suitably linked with each other and with terminal 104. The rotatable cam 102 is normally moved manually by a knob in the outer surface of the timer casing in order to begin a cycle of operation, movement of that knob serving to wind a spring motor or equivalent means (not shown) which thereafter causes the cam to move during a selected time period to a starting position for the next cycle and at which starting position both switches will again be in open circuit condition.

When the operator sets the timer for supply of either air, or air and steam jointly, switch 96 is closed and a circuit is made from lead 40, relay terminal 92, conductor 103, timer terminal 97, through switch 96, timer terminals 98, 101, 104, conductor 105, relay terminal 95, solenoid 93, relay terminal 94 and return lead 41. Relay solenoid 93 then closes arm 89 upon relay terminal 90 and a shunt circuit is then made from lead 40, arm 89, relay terminal 90, conductor 106, 'motor 13, conductor 107, relay terminal 94 and return lead 41. The motor 13 driving blower 12 will continue to run so long as switch 96 remains closed.

If cam 102 has been turned only sulficiently to close switch 96, but not switch 99, then only air is supplied to the finisher and the steam valve solenoid remains inoperative. If, however, the cam has turned sufficiently to close switch 99, then, in addition to the described circuits, another circuit is simultaneously made from lead 40, relay terminal 92, conductor 103, timer terminal 97, switch 96, timer terminals 98 and 101, switch 99, timer' terminal 100, conductor 108, terminals 33 and 34 on the steam solenoid 32,.relay terminal 94 and return lead 41. Solenoid 32, of course, is later inactivated as soon as the cam uncovers the follower of switch 99 and permits it to reopen. In addition, after the cam uncovers the follower of switch 96, as when the drying cycle is completed, the circuit through the relay solenoid is reopened and relay arm 89 returns to its normal position breaking contact with relay terminal 90 and opening the shunt circuit to motor 13 which then comes to rest;

Referring now to FIGS. 7 and 8, the air conduit includes spaced side walls 43 and 44, a top wall 45 and a bottom wall 46, which preferably has an inclined portion 47. Afiixed to a transverse rod 48' journalled in the side walls of the conduit is an improved damper 49 which may comprise sheet metal, This damper extends substantially across the entire conduit, but has its side edges terminating a slight distance from the side walls thereof to provide narrow slits 50 and 51 which permit air to bleed through the damper even when the apparatus is not being operated. As will be apparent to those skilled in the garment finisher art, the conden sation of steam upon metal parts following the conclusion of an operation may soak portions of the bag 14 with liquid and may contribute to the non-uniform finishing of the subsequent garment under treatment. Since steam in coil 22 is constantly available as a source of heat, a substantial convection current of air is permitted by my invention and this heated air constantly fills the interior of the bag between successive garment treatments. Such air of course, enters through blower 12, even when at rest, bleeds through slots 50 and 51 in the damper, passes over coil 22, and rises into the interior of the bag. Preferably, the damper also is provided with small cut away upper corners 52 and 53 to aid in the flow of air at the minimum setting of the air controller later to be described. In order, however, to insure a predetermined volume of air flow at that minimum setting, I provide improved seals which serve to limit air flow to the open spaces afforded by slots 50 and 51 and corners 52, 53. As a feature of the invention, the damper is automatically operable and requires no continued attention of the operator. Due to being mounted off-center upon rotatable rod 48, the damper normally falls to closed position as seen in solid lines in FIG. 7, under the bias of gravity, but, if permitted by its position control arm, as will later be described, will rise to fully open position, as seen in dotted lines,

under the pressure from blower 12. At its upper edge, I provide a curved portion 54 adapted to seat against a felt washer 55 carried by an adjustable plate 56 suitably mounted in slots in a partition 57, extending downwardly from the top wall of the air conduit. Similarly, at its lower edge, a curved portion 58 rests upon a felt washer 59 carried by an adjustable plate 60 suitably mounted in slots in a partition 61 extending upwardly from the inclined bottom wall of the conduit.

With the above description of the damper in mind, reference now is made to FIGS. 3 to 6, inclusive. At the end of rod 48 adjacent the solenoid enclosure 19, a damper position control arm 62 terminating in a flat abutment portion 63 is provided. In closed position, this arm is spaced from the solenoid enclosure and in open position closely approaches that enclosure. As the arm moves to open damper position, however, it travels in the plane of an arresting extension 70 mounted upon a lever 71 which is pivoted at its lower end upon a pin 72 mounted in a projection 73 extending to one side from the bottom of solenoid enclosure 19. This lever may include a stepped configuration placing the upper end thereof inwardly of the lower end thereof and closely adjacent the side wall 43 of the air conduit. Connected to the upper end of lever 71 is a flexible pushpull wire 74 extending from a rigid guide tube 75 mounted in a bracket 76 attached to wall 43. The Wire, in turn, is encased in the tube 75 to a point closely adjacent the air controller 18 (FIG. 2) but with the final portion of the wire being exposed near its connection to that air controller in order to permit flexing of the wire about a comparatively short radius without binding in the tube.

As noted in FIGS. 1 and 9, the air controller comprises a segmental disc-like plate member having an arcuate face portion and pivotally mounted for rocking movement upon a stationary pin 77 projecting laterally from tubing 16 adjacent the timer 17, which tubing provides a rigid support for the controller and at a convenient height. On its face portion, this controller is provided with indica indicating visually to the operator the position of wire 74 and thereby the position of lever 71 and its arresting arm 70 at any given time. A compression spring 78 surrounding pin 77 and bearing against the controller body prevents slippage or inadvertent movement of the controller while forward and rearward stops 79 and 80, respectively, adapted to engage the body of timer 17, limit the movement of the air controller settings and reduce stresses upon lever 71 and upon the damper when engaged by the arresting arm 70. A short handle 81 is provided at one arcuate extremity of the air controller for manual use and at the other arcuate extremity a pin 82 is rotatably journalled in the end of stop 80 and has securely anchored thereto the end of push-pull wire 74.

Accordingly, with the air controller positioned with stop 79 in engagement with the timer housing, lever 71 is fully extended as seen in FIG. 3, the arresting arm 70 is in contact with damper control arm 62 holding the damper in fully closed position even against the pressure of air from blower 12, and a condition of minimum air supply, such as may be needed when a garment of sheer fabric is being processed, thus obtains. However, due to the construction of the damper, sufiicient air is supplied to the bag to distend the same and to dry the garment.

Upon successive settings of the air controller with ,stop 79 farther and farther away from the setting for As shown in FIGS. 3 and 4, I provide a shift lever 36 pivotally mounted at its upper end upon a pin 85 projecting from the end of solenoid enclosure .19 and permitting swinging movement of the shift lever in a plane normal to the plane of movement of both the damper control arm 62 and of the lever 71. Extending from the shift lever is a cam member 86, here shown as being of conical form, and normally held in the path of movement of stepped lever 71 as that lever reaches its position of maximum air supply. A tension spring 87 attached at one end to the bottom of the shift lever and at the other end to the base assembly holds the shift lever in position for such engagement with lever 71. At its bottom portion, the shift lever guides the movement of damper-control-arm-engaging rod 35 which normally is in the same plane as the movement of damper abutment 63. Accordingly, when timer 17 energizes both motor 13 and'solenoid 32 simultaneously, and with the air controller positioned at a setting between minimum and maximum air supply, as above described, the energization of the solenoid 32 pulls rod 35 to the right in FIG. 3 against abutment 63 on the damper arm and holds the damper closed until the solenoid 32 is dc-energized. In this way, the garment is first subjected to a processing fluid consisting essentially of steam and before being subjected to the full pressure of heated air. In general, most garments may be most eficiently finished by this cycle, the steam being supplied for about 8-10 seconds and being followed by an air drying treatment of about 60 seconds.

In accordance with my invention, I am not limited to this conventional cycle of treatment and when treating garments requiring both steam and full air pressure simultaneously, may readily supply these processing fluids merely by adjusting the air controller 18 in advance. By moving the air controller until stop engages the timer housing, the wire 74 is pulled outwardly to a position at which a stepped portion of lever 71 engages against cam 86 and forces that cam to one side. As this occurs, shift lever 36 is pivoted about pin and the bottom of the lever swings outwardly bringing the path of travel of rod 35 out of the plane of damper abutment 63. Thereafter, when the timer energizes the motor and solenoid 32 simultaneously, rod 35 passes by arm 62 and the damper rises to fully open position While steam is being supplied to the interior of the bag. The combined effect of steam and full air pressure serves to drive the steam quickly into the garment positioned on the bag and to shorten the time required for finishing a garment of the more difficult types above mentioned.

If the next garment to be finished is of a delicate material, the air controller is then reset to give a limited air pressure and spring 87 automatically returns the shift lever into normal position at which rod 35 is guided into contact with the abutment 63 to prevent steam and full air pressure being supplied simultaneously and which might damage the delicate material.

It will now be apparent that by this invention, I am able to increase the capabilities of a garment finisher to handle a wide variety of types of garments on the same machine in an efiicient manner and without diminishing the advantages found in the garment finisher described in copending application, Serial No. 586,710.

To recapitulate, the objectives of the invention are thus accomplished since by means of the timer, the solenoid 32 and the motor for the blower are, during any given cycle, both energized initially simultaneously. The steam valve is opened while the solenoid 32 is energized, but the damper may selectively be either open or substantially closed While the steam is being supplied to the garment, depending upon the prior positioning of the shift lever. Even when that lever is set to hold the damper closed during steam supply, the damper itself permits sutficient air to bleed therethrough to minimize condensation of the steam upon the parts of the apparatus and to force the steam with a light pressure through the bag and into the garment.

Conversely, when the lever is set to permit full opening of the damper during steam supply, full air pressure may be applied to the bag and garment along with the steam and thus, the steam is forced into the garment, even though it may be of a heavy material, such as suede or chamois. When the solenoid 32 is deenergized, the steam valve is closed and the damper-control-arm-engaging rod 35 is withdrawn. The blower motor, however, remains energized, due to the timer setting and the damper then swings open to the extent permitted by the prior positioning of lever 71. So long as the motor continues to operate, heating air is then forced into the bag for drying the garment. Even after the motor stops operating, air bleeding through slots 50 and 51 in the damper rises by convection currents into the form and serves to minimize condensation of moisture.

While I have shown a particular embodiment of the invention it will be understood, of course, that I do not wish to be limited thereto, since many modifications may be made. I, therefore, contemplate, by the appended claims to cover any said modifications as fall within the true spirit and scope of my invention.
